To differentiate the chloro-
phyll-a content and for
the determination of the
phaeophytin-a content,
acidify a portion of the
extract with hydrochlo-
ric acid 2 mol/l Titripur
®
(Cat. No. 109063) (0.3 ml
per 100 ml of extract).
Transfer the solution into
a corresponding cell.
Place the cell into the
cell compartment a
nd
measure anew.
